“…In determination of the thermal resistance (R), the lost heat transfer coefficient (h Loss ) was obtained by the heat loss estimate, and the estimate method of heat loss (Q Loss ) is shown in literatures [13,14]. The experimental uncertainty was analyzed by uncertainty of a single experiment by Moffat [15].…”

“…Another way is to change the material of the heat sink, including the fins and substrate [ 13 , 14 ]. Porous medias such as micro tubes [ 15 , 16 ], sintered metal [ 17 , 18 ] and metal foam [ 19 , 20 ] are very popular fin materials in research because they have very large convection area. The orientation direction of the heat sink in application [ 21 , 22 ] and airflow condition [ 23 , 24 ] were also found to have impact on cooling efficiency.…”

Heat sinks are widely used in electronic devices with high heat flux. The design and build of microstructures on heat sinks has shown effectiveness in improving heat dissipation efficiency. In this paper, four kinds of treatment methods were used to make different microstructures on heat sink surfaces, and thermal radiation coating also applied onto the heat sink surfaces to improve thermal radiation. The surface roughness, thermal emissivity and heat dissipation performance with and without thermal radiation coating of the heat sinks were studied. The result shows that with an increase of surface roughness, the thermal emissivity can increase up to 2.5 times. With thermal radiation coating on a surface with microstructures, the heat dissipation was further improved because the heat conduction at the coating and heat sink interface was enhanced. Therefore, surface treatment can improve the heat dissipation performance of the heat sink significantly by enhancing the thermal convection, radiation and conduction.
